Abstract: 1,104,240. Machines for de-husking nuts. A. NAKANO. 25 Oct., 1966 [8 Nov., 1965], No. 47828/66. Heading A2Q. A machine, Figs. 1 and 4, for removing husks, but not shells, from nuts, such as Macadamia or Queensland nuts, comprises a pair of rotatably mounted, parallel rollers 13 and 18 provided with helical scrolls 11 and 12 for conveying nuts away from a feed hopper 27 located above the half-way point along the rollers where the pitches of the scrolls are reversed, a pulley 24 and a gear-box 23, located at the front of the machine, for rotating the rollers in opposite directions, and elongated pressing devices 38 and 39 made of relatively stiff, yieldable, elastic material, e.g. moulded rubber reinforced with nylon cords, disposed over the path of the nuts to break their husks and force the husks into the nip between the rotating rollers, so that husks are stripped from the nuts and deposited in a receptacle (not shown) located under the rollers. The de-husked, in-shell nuts are carried along the scrolls and delivered from the front and rear ends of the rollers, into .receptacles (not shown). The lower edges of the front and rear ends, 29 and 28, of the hopper are formed with arcuate portion 34, 35 and 36, leaving openings 37, through which nuts pass, one at a time, from the hopper on to the rollers. The helical scrolls project slightly more from the parts of the rollers under the hopper than from the remaining parts of the rollers. Each device 38 and 39 is preferably U-shaped in cross-section, and its bight is directed towards the nip between the rollers. The end of the bight near the opening 37 may be notched, to facilitate reception of nuts, singly, from the hopper. The bight may also be notched, substantially half-way along each device, to allow a trapped nut to turn and reposition itself, thus facilitating de-husking.

The connection of the overlay transmitters to the track is adjacent the receive pick up coils, e.g. 26 of the main track circuit. The cab signals are picked up by pick up coil 82 on the train in the approach to the connection point and on the train the signals are demodulated 84, decoded 86 and applied to a drivers display 88 which is self latching to retain the display until the next signalling location is reached.

The wax/spiropyran may be dispersed in a polymer before coating. The material is first heated to above the melting point of the wax and to sensitize the layer exposed to ultraviolet to give a magenta colour and then heated again to give a fixed blue colour, one of the three steps being imagewise. The magenta colour may be erased by exposure to green light or light of a longer wavelength and the blue colour may be erased by prolonged heating. An image can thus be produced by using various combinations of heat, ultraviolet and green light. A second image may be added to the first image by repeating the heating, ultraviolet exposure and heat-fixing steps. The waxes specified are ethylene glycol monostearate; paraffin, microcrystalline carnauba or bees-wax; spermaceti or fatty acid esters.

A vehicle, which may operate both as an air cushion vehicle or as a displacement vessel has a flexible inflatable understructure which may in the one role assist in containing an air cushion and in the other role may provide buoyant support for the vehicle, and is constructed to form an upper portion and a lower portion, said upper portion being retractable when the vehicle operates in the air cushion supported role. As extended to provide buoyancy, as shown in Fig. 2, each understructure comprises upper inner and outer side panels 15, 18 attached at 16, 19 to the base structure 10 and attached at 21, 20 to a looped flexible lower panel 22 and to a transverse flexible diaphragm 33 formed on its outer portion with apertures 34. A further flexible looped member 35 is secured inside panel 22 at 36 to panel 33 inboard of apertures 34, and at 37 to panel 22 inboard of an aperture 23 formed in the panel for discharge of curtain air inside segmented skirt members 14, shown collapsed in Fig. 2 and extended in Fig. 1. Air for pressurizing upper chamber 12 is delivered through a rigid duet 25 in body 10 and air for pressurizing lower chamber 13 is delivered through a vertically collapsible duct 24a which discharges through panel 33 and forces member 35 into the position of Fig. 2 to seal off aperture 23. In the air cushion role air supply to ducts 24a, 25 is shut off and cables 38, 39 retract upper panels 15, 18 as shown in Fig. 1. A closed valve 26 in an air duct 17 is opened to supply curtain and cushion forming air, which flows through apertures 34, moves member 35 across chamber 13 to expose aperture 23 and forms a curtain as shown by arrows. In a further embodiment (Fig. 3, not shown) the inner and outer walls are formed in a single continuous loop connected by a fully apertured transverse panel to form upper and lower pressurized compartments, the lower skirt segments being inflated by pressure air within the cushion.
